Abstract (en)

Polyhydroxybutyric acid polymers or copolymers of hydroxybutyric acid and hydroxyvaleric acid may be used for preparing a porous, bioresorbable flexible sheet for tissue separation and stimulation of tissue regeneration at healing processes in injured soft tissue in mammals including man. The sheet has a pore size permitting passage of water and salts through the sheet but which locks out cells and other tissue particles. Processes for preparation of the material and are also described.
